Florida-based Harris reported income from continuing operations of $142 million, or $1.25 a diluted share, compared with $136 million, or $1.18 a diluted share, a year ago. Excluding special charges, income from continuing operations was $142 million, or $1.24 a diluted share. Sales were $1.29 billion, down from $1.31 billion a year ago.

Due to expected slower government spending resulting from growing budget uncertainty, Harris has updated its fiscal 2013 guidance for income from continuing operations to a range of $5 to $5.20 a share from a range of $5.10 to $5.30 a share. Revenue is now expected to decline 2 percent to 4 percent compared.
